IUG: Revived

This is a remake of Incremental Universe Growth by -Danielt- and me (Quasitruncated Hexahedron). That was never finished as Replit shut down the original .repl.co domains on January 1st, 2024. I did move it to GitHub (of which my account there has since been terminated - thankfully, I'm 13 now, don't worry), but that eventually ended following the insane backlash from the game's poor reception on Galaxy, an incremental sharing platform, mainly over the extremely long timewalls and poor balancing.

That was in turn the spiritual successor to Universe Expander, a Scratch incremental made by the same person. The name was changed for already being taken.

Credit goes to the following people for parts of this project:

Patashu, for break_eternity.js
MathCookie, for both Eternal Notations and The 2048 Power Compendium, of which the latter's save codes were used as inspiration for how text saves work in this game.

Full changelog

v0.3.3 [January 18th, 2025, 3:11 PM GMT]

Added in a refundable - buyables which you can "unspend" (not a true refund, since you don't get anything back). Also, the upgrade itself may be temporary, because I was running out of ideas.
Made challenge 7 hidden until objects are reached (It still isn't possible though)
Speaking of challenge 7, continued the tradition of teasing the next update through a button which has an alert popup explaining what the next update will add
Implemented in some Subjective Milestones

v0.3.2 [November 30th, 2025, 04:00 PM GMT]

Added object buyable 1
Fixed a glaring oversight involving the cost scaling of upgrade 4
Made Subjective milestones weaken dark matter buyable 1's cost scaling

v0.3.1 [November 29th, 2025, 11:51 PM GMT] - The Update which ended the streak of me procrastinating

Heavily nerfed the object requirement
Added Subjective Milestones. These are probably impossible at the moment (and very unfinished at that), but that's expected when the boosts from the previous Subjective Milestone that allow you to get the next Subjective Milestone don't even exist yet.
Insert procrastination apology here
Added a (temporary) favicon

v0.3.0a [August 31st, 2025, 00:55 AM GMT]

Intentionally keeping challenge 7 impossible so I can use it for the "Antimatter ?????????" listed below

v0.1.0 [June 2nd, 2024, 09:49 PM GMT] (yes, really)

Initial version
Only universe size and upgrade 1

Size: Primary currency. Everything ultimately depends on your univere size.
Main Upgrade: Have an immediate effect on your growth. Upgrades are always numbered top-to-bottom, left-to-right.
Antimatter: Softcap beginning at 1,000,000m shut up I'll format this later.

Dimension: Prestige mechanic which gives an additional boost (specifically ^sqrt(# of dimensions))
Automation: Prevents you from having to click 1,000 times. Except for the first one, can be enabled/disabled

Dark Matter: Additional, second-layer currency
Upgrade/Buyable: Buyables can be respent, upgrades cannot.

Challenge: I have officially run out of things to say

Object: A third layer currency
Subjective Milestone: reset within a dimension and without going over the reset req
Refundable: Any buyable that can be unspent. There is no requirement on if you get your money back.
Your Next Goal: merge these all into one page instead of mutliple subpages probably

Either progression or things you might want to go for, all for only bragging rights

You have 0 dark matter, boosting your universe growth ^1

You have 0 challenge completion(s), giving a ^1 boost to your dark matter boost.
All challenges disable both dark matter upgrades and can be completed up to five times.

You have 0 object(s), boosting your dark matter growth ×1

Gain objects within a certain number of dimensions to gain a reward! Each subjective milestone also weakens the cost scaling of the first dark matter buyable. You also have to not be able to reset to over that dimension. So if you're at dimension 6 and have gone up to 1e140m, if you reset for objects you still wouldn't get the subjective milestone because you have been high enough to reach dimension 7. Note: Many of these are likely impossible at the moment and also do not give out any rewards.

∞ Dimensions Automatically gain 1 dark matter per second	45 Dimensions Base dark matter gain is raised ^1.1	30 Dimensions Unlock Antimatter Hellscapes	25 Dimensions ???
20 Dimensions ???	15 Dimensions Unlock Objective Challenges	12 Dimensions ???	10 Dimensions ???
6 Dimensions ???	1 Dimension ???, and exponentiate your universe growth
